Are we really to believe that we would sent 8 people off into space to certain death with no prospect of getting back?
That seems to be the idea behind this episode - getting back is no longer an option. Or have I picked it up wrong?
I can understand long voyages being undertaken, but not one where they would not get back - wives and husbands and children appear to be waiting. I thought the idea was it was a six year mission or something. Not a 'point of no return' situation.
